Answer:
Explanation:
Mass of person = 50 kg
Weight of the person = 50 × 10
= 500 N (If g= 10m/s²)
Height at which the person is standing = 10 m
Potential Energy of Person = m g h
= 500 × 10
= 5000 J
ADDITIONAL POINT - The work done by gravity doesn't depend upon what path the object has took to reach the ground, it is always the same in all the cases that is, equal to the F · d of the body = m g h.
